Laravel > route, filter URL against database

I'm trying to build the new version of our site with the Laravel 5 framework.

The problem is, we have now the following site structure (and this may not be changed):

• http://ift.tt/1LEkohE] <- dynamic
• http://ift.tt/1PWJqM6] <- dynamic
• http://ift.tt/1LEkmq0
• http://ift.tt/1PWJonr
• ....

In our database, we have a list of different product names and different categories.

I want to route the [productname] to a productController and the [categoryname] to the categoryController. But therefor, i need query our database with each request to see if the URL parameter is either a product or a category.

Any ideas to get me on right direction?

Thanks in advance!
